Gas Range

I have 200 of these to maintain. I have had a couple in the bake mode… start , heat up, maintain temp, and then either shut off or just stop heating. Inconsistant problem.

Is there a diagnostic mode on this unit ?

Are there ohm readings I can take on the gas valve coils ?

Could it be the ignitor fails after so long in the flame ?

Please Help. Let me know what you think.

Here is the tech sheet for them. Maybe you will find the diagnostic information helpful.
